1. A laser delivery device, comprising:
an optical fiber, including a proximal portion configured to be coupled to an energy source and a distal portion opposite the proximal portion; and
a capillary surrounding at least a portion of the optical fiber and including a proximal portion and a distal portion,
wherein the capillary includes a first portion that includes one or more of dimples, bumps, or internally dispersed particles and a second portion that is free of dimples, bumps, or internally dispersed particles, wherein the second portion is at the proximal portion of the capillary, and
wherein the capillary is fused to the optical fiber over at least a portion of an overlap of the second portion of the capillary and the optical fiber.
